Altimeter and Barometer on Gear S3

A

AC Question

Hi all,

Does anyone know how to set the Altimeter and Barometer correctly on a Gear S3?...My Frontier is way off and even after turning GPS on it still gives the wrong reading.

Ironically, my Note 4 which runs the Compass App show the correct Altitude.

It appears that this is an Accuweather sync issue as my son's S5 Active shows the exact same information as my Gear S3 (both take info. from Accuweather).

Thanks in advance to the community.
